SMELTER SPO'UT.

Application filed November 11, 1925. Serial No. 68,379.

This invention relates to apparatus used in smelting, and has for itsobject the provision of a novel water cooled spout so constructed. andlined with such material as to resist the action. of alkalies and heatso that the spout will be particularly well adapted for use on smeltersburning black ash to cover chemicals used in the manufacture of sulphateand certain pulps.

An important object is to provide aspout of this character which will besimple and inexpensive in manufacture, easy to use, efficient in serviceand a general improve ment in the art.

With the above and other objects and ad vantages in view, the inventionconsists in the details of construction, and the arrangement andcombination of parts to be hereinafter more fully described and claimed,and illustrated in the accompanying drawings, in which Figure 1 is aplan view of the device.

Figure 2 is a longitudinal section taken on the line 2-2 of Figure 1,and 5 Figure 3 is a cross section taken on the line 3-3 of Figure 1.

Referring more particularly to the drawing's, we have shown the deviceas of semicylindrical shape and including an outer section 10 of metaland an inner section or lining 11 of refractory material capable ofwithstanding great heat and capable of withstanding the action ofalkalies or the like.

As a matter of construction, the outer section or casing 10 may beformed as a piece of stand pipe ou in two lengthwise while the innersection or lining 11 may be formed from a piece of refractory pipe oilless diameter likewise cut longitudinally. Regardless of this detail,the out-er and inner sections are spaced apart at their ends bysemi-circular spacing members 12 of metal, and are spaced apart at theirlongitudinal edges by bars or strips 13 which are likewise of metal andwelded or otherwise suitably secured in place.

The provision of the spacing members 12 and. 18 defines a chamber 14between the outer and inner sections, which chamber is adapted tocontain water for cooling purposes, the water being admitted to and discharged from the chamber through the pipes 15 and 16.

In the operation, it will be seen that the device is used in exactly thesame manner as any other spout but it has the great ad vantage oi. beingwater cooled and consequently more durable than the ordinary typeespecially in view of the provision of the lining or inner section ofthe refract'ory material. It is believed that the construction,operation and advantages will be readily apparent to one skilled in theart without further explanation.

lVhile we have shown and described the preferred embodiment of theinvention, it should be understood that we reserve the right to makesuch changes in the form construction and arrangement of parts as willnot depart from the spirit of the invention or the scope of thesubjoined claim.

Having thus described the invention, we claim:

A smelters spout of so1ni-cylindrical formation comprising; a metallicouter section, an inner section of refractory material coextensive inlength with the outer section, spacing means located between saidsections at the ends thereof, other spacing means located between saidsections at the longitudinal edges thereof. the provision oi? thespacing means defining a chamber between the outer and inner sections,and water inlet and outlet pipes leading into said chamber.

In. testimony whereof we afiix our sig i tures.
